Genetic characterization of adult infratentorial gliomas.
Article in Journal of neuro-oncology, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Adult infratentorial gliomas are rare and have not been well studied. We therefore conducted genetic analysis of those tumors to see if there was any characteristic that could be relevant in clinical management and understanding of tumorigenesis. Nineteen adult infratentorial gliomas were analyzed for chromosomal aberration by comparative genomic hybridization, and for expression of p53 and epidermal growth factor receptor (EGFR) by immunohistochemistry. The most frequent chromosomal aberration was the gain of 7p, and five of the seven cerebellar or fourth ventricle malignant gliomas had that aberration. However, the gain of 7q, the characteristic abnormality of supratentorial astrocytomas commonly associated with the gaining of 7p, was observed only in 1 of 11 adult infratentorial astrocytic tumors. Combined losses of 1p and 19q, the genetic hallmark of oligodendroglioma, were not observed. Results of immunohistochemistry of p53 and EGFR were comparable to those reported in supratentorial gliomas. Our findings might suggest the presence of distinct tumorigenic pathway in adult infratentorial gliomas.
